Re-greasing the Ultra motor...is it time?

[Tom@WashDC]

So we are currently in a very cold stretch here and I find no enjoyment in layering up to ride.... That and the MUP is a sheet of ice.
So I opened up a new Quiet Gear Ultra with just 100 miles on it...Note, I don't find it to be any quieter than my 2022 motor.

The amount of factory grease seemed adequate but was the same yellow seen before but had mostly black'nd in color and quite frankly looked burnt and wasn't easy to clean up.

So cleaning it up was tedious but with patience doable

Put back approximately the same amount of Cornhead grease and about the same as I had used on the 2022 motor when I used the Mobile SHC100

I found the Cornhead very hard to work with and to be neat with. It has a very tacky property and it's like working with snot.
This also lead me down the path of making a mistake. Not wanting to have two very different greases in the motor I also lifted the main large gear to lube the pawl clutch with the cornhead. And though I used as thin a layer as possible.. When reassembled the pawl clutch didn't work correctly due to the tackyness of the grease. Luckily I bench tested it and found out then. So I cleaned it up again and used some Mobil SHC100 which didn't give me the same problem. The greases are far enough apart so they shouldn't contaminate each other (hopefully)

This now done its still not favorable outside to ride and the temperature still hasn't risen above freezing. Hopefully it'll change soon and I'll get out in the next week.

First impression.. If the cornhead doesn't provide a much quieter motor, I'll stick with the Mobil.

I feel for you. I'm hating this weather. I don't mind bundling up. I use fur lined pogies without gloves. I just hate ice. Do not want to go down on ice.

Curiosity got the best of me so I ventured out for a short 5mi ride.
The MUP is still a sheet of ice and the streets have enough ice melt salt on them to start your own Dead Sea... But at least the temps made it to 40° this afternoon for the first time in too long.
This said and my first impression... I'm not experiencing the Quiet Gear nor Corn Head Grease miracle.
Probably measurably quieter but no where near what I would consider to be quiet motor. If you've ever riden with a BBS02B... Now that's near silent.
I'll give it a few more miles and see if things get quieter with break in like they did when I initially tried the Mobil SHC100
I may then open her up to check migration and possibly top it off as I've seen many on here with cornhead grease pics and much more grease was used.

Hey @JRA ... You speak of only using a tblsp and I'd guess that's about what I used.. How do my pics compare to the amount you used?

Sounds to me like you may be experiencing premature coagulation as a result of greasing your own bafang

No one would know better than you Black Hand.
What's truely amazing is that you taught the dog to reach all those tricky bearings that you so desperately tried to reach but just couldn't.

SO I'll ask again,
What do you use to clean to clean out to old grease and WILL NOT harm anything inside, like all those electrical boards/wires etc?

Paper towels, a cloth rag and a small plastic brush.
Alcohol wipes to finish up and for anything electrical that may get grease on it.
